SUPPORTING-BRACKET FOR MESSENGER-WIRES.

SPECIFICATION forming part of Letters Patent N 0. 782,366, datedFebruary 14, 1905.

' Application filed October 5,1903. Serial No. 175,834.

To aZZ whom it may concern:

Be it known that I, HAROLD D. STROUD, a resident of Chicago, in thecounty of Cook and State of Illinois, have invented certain new anduseful Improvements in Supporting-Brackets for Messenger-Wires, of whichthe following is a specification.

This invention relates to improvements in brackets, and refers morespecifically to a bracket specially adapted for supportingmessenger-wires or the like.

Among the salient objects of the invention are to provide a constructionin which a single clamping-bolt serves to hold the clamping memberrigidly and securely in position, to provide a construction in which allparts are permanently connected, but nevertheless susceptible ofadjustment to release the wire or other cable supported thereby, toprovide a construction of the utmost simplicity and maximum strength,and in general to provide a simple, eflicient, and convenient device ofthe character referred to.

To the above ends the invention consists in the matters hereinafterdescribed, and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a side elevation of a bracket embodying myinvention,the parts bein shown in erative osition and a or,- u h tionbeing broken away and shown in section to disclose the manner ofsecuring one end of the clamping-plate. Fig. 2 is a front elevation ofthe parts shown in Fig. 1. Fig. 3 is a top plan view with theclamping-plate thrown out of operative position in readiness to removethe messenger-wire.

In the drawings, 1 designates, as a whole, the main body of the bracket.which is of L shape, the vertical member being provided with suitablebolt-apertures 2 and the lower or horizontal member provided in itsupper side with a transverse groove or seat 3 and also with aclamping-bolt aperture 4. designates a clamping lever-plate, which, asbest seen in Fig. 3, is provided at one end with a clamping-boltaperture 6, adapted to register with the aperture 4 of the bracket andat its opposite end with a lug or extension 7. The lug of theclamping-plate 5 is adapted to extend beneath and engage an overhangingshoulder 8, said shoulder being in the present instance provided byforming a socket 9 in the upright portion of the bracket adaptedtoreceive the lug 7. Upon its under side the clamping-plate is alsoprovided with a transverse groove or seat 10, arranged to register withthe groove 3 when the parts are in operative position, the combineddepth of the grooves 3 and 10 being less than the diameter of the wire11 to be supported, so that when the latter is in position the clamping-plate will be held separated or spaced away from the upper surfaceof the horizontal member of the bracket.

12 designates a clamping-bolt, which is preferably made considerablelonger than sufii- -cient to extend through the superposed parts of thedevice in order that the bolt may be retracted sufficiently to releasethe plate from clamping engagement without entirely removing the bolt.The end of the bolt is preferably headed slightly, as indicated at 13,so

that it will not readily pass through the nut 14. Desirably, also, theshank portion of the bolt which occupies the aperture of the plate 5 issquare or non-cylindric, and the aperture 6 is made of a width to fitthe sides of the nut, so as to prevent rotation of the latter. Thebolt-aperture of the plate 5 is, however, elongated or of slot form topermit the lug 7 to be retracted from the socket 9 without removing thebolt.

The use of the device is probably obvious from the foregoingdescription, but may be briefly described as follows: Assumingthat thevertical portion of the bracket has been secured to a suitable support,the clamp 5 is rotated on a bolt 12 from its normal position ahalf-revolution, so as to expose the seat or groove 3, whereu pon themessenger-wire is adjusted to position, the clamping lever-plate rotatedback to bring its lug into alinement with the socket, and then shiftedend wise to engage the lug with the shoulder 8. Thereupon theclamping-bolt is tightened, so as to clamp the messenger-wire firmlybetween the horizontal member of the bracket and the clampinglever-plate. The operation of removing the messenger-wire from thebracket is obviously the reverse of that just described.

While I have herein shown and described a preferred embodiment of theinvention, yet it will be understood that the details of constructionmay be modified without departing from the invention.

I claim as my invention 1. A bracket comprising a generally L- shapedmain body, a clamping-plate arranggL to overlie one member of said mainbody, a socket carried by the other arm of the bracket arranged toreceive and confine against both lateral and upward movement one end ofsaidclampingplate, a clamping bolt extending through the opposite end ofsaid clampingplate and a subjacent support, and a cableseat formedbetween said clamping-plate and the part of the bracket overlaid therebyat a point between said confining-socket and the clamping-bolt.

2. A supporting-bracket comprising a back member adapted to be securedto a suitable support, a projecting supporting member, a clampinglever-plate arranged to overlie the supporting member, a shoulderarranged to confine one end of the lever-plate, a clampingbolt extendingthroughthe other end of the clamping-plate and subjacent support and acable-seat between the clamping-bolt an opposite end of the lever-plate,the confining connections of said clamping lever-plate being constructedto permit said plate to swivel upon the clamping-bolt to a position outof register with the cable-seat, when the clamping-bolt is loosenedsbutnot disconnected.

3. A bracket comprising asupportin g mem her, a clamping-plate overlyingthe supporting member and arranged approximately parallel with thelatter, means positively confining one end of said clamping-plateagainst movement in a direction away from the subjacent support, and aclamping-bolt extending through the opposite end of the clampingplateand subjacent support, the bolt-aperture in said clamping-plate being ofslot form to permit disengagement of the positively confined end of theplate by endwise movement of the latter, for the purpose set forth.

4. A bracket comprising an L-shaped main body, a clamping-plate arrangedto overlie one member of said main body, a shoulder arranged upon theother arm of the bracket arranged to overhang and confine one end ofsaid clamping-plate, a clamping-bolt extending through the opposite endof said clam pingplate and the subjacent support, the clampingbolt beingarranged sufficiently near one edge of the clamping-plate to carry theclam pingplate out of register with the holding-seat when loosened andpartially rotated upon the bolt, substantially as and for the purposeset forth.

5. A bracket comprising a supportingmemher, a clamping-plate arranged tooverlie the supporting member and provided at one end with a lug, meanspositively confining said lug against rotary movement and againstmovement in a direction away from the subjacent support, and a clampingbolt extending through the opposite end of the clamping-plate andsubjacent support, the bolt-aperture in said clamping-plate being ofslot-like form to permit endwise shifting of the plate to disengage itslug from said confining means, for

the purpose set forth.
